Specification of Letters Patent.

Patented June 8, 3215.

Application filed December 1a, 1914. Serial no. 877,089.

To allwhom it may concern.

Be it known that I, FRANK SMITH, a citizen of the United, States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Stoves, of whichthe following is a specification.

My invention relates to improvements in stoves, and more particularly toan attachment to replace the ordinary tops'of stoves; and one object isto provide a device'of this character having an internal arrangementwhereby equal distribution of heat throughout the top of the attachmentis bad, thereby rendering it especially desirable for laundry, cooking,and heating purposes, and efiecting economy of fuel.

A further object is to provide a device of this character having a fiattop of larger area, than the stove top it replaces, so that it canreadily accommodate wash-boilers, fiat-irons, cooking utensils, etc.

@ther objects of the invention will hereinafter appear, and in orderthat said invention may be fully understood, reference will now be madeto the accompanying drawing, in which Figure 1 is a front elevation of astove provided with my attachment. Fig. 2 is a vertical longitudinalsection of the attachment and the upper portion. of the stove. Fig. 3 isa vertical cross section of the attachment on line III-JET of Fig. 1.Fig. 4 is a plan view of the attachment with its top plate removed. Fig.5 is an inverted plan view of the top plate of the attachment. Fig. 6 isa plan view of an inner chamber constituting partof the invention.

A designates a stove of ordinary construe tion with its usual top plateremoved.

1 designates my attachment which is substituted for the top plate of thestove.

2 designates an outer chamber of the attachment, consisting of a bottomwall 3 and a surrounding side wall 4, preferably, of elliptical form asdisclosed by Fig. 4. The front portion of the side wall 4 has aforwardly extending hopper 5 through which fuel may be fed to thefire-pot of the stove A. The hopper 5 is normally closed by a door 6,operably connected at its upper end to a top plate 7. The rear portionof the side wall 4 has a bay 8, for communication with an outlet 9 inthe rear portion of the top plate 7. p

10 designates an inner chamber surrounded by a concave inner wall 12,which flares upward to its juncture with a surrounding side wall 11, asdisclosed by Fig.2. The side wall 11 is of substantially the samecontour as the side wall 4, from which it is spaced to leave anintervening continuous flue 13, formed by the walls a and 11, the bottomwall 3 and the top wall 7. A dead space 12 is left between the walls lland 12,

and as it is closed at its ends no draft or circulation of air passestherethrough.

The chambers 2 and 10 are provided at their bottomportions withregistering openings 1d and. 15, respectively, preferably, of accircular form and communicating with the upper open end of the stove A,as disclosed by Fig. 2, for the free upward passage of the products ofcombustion from said stove The inner chamber 10 is provided at its frontand rear sides with outlets l6 and 17, respectively, which counicatewith opposite sides of the fine 13. The outlet 16, is, preferably, leftopen at all times, but a valve 18 is provided to close the outlet 17 1when desired. The valve 18 is fixed to a pintle 19, journaled in thewalls a and 11, and provided at its outer end with a handle 20. Thevalve 18 is reliably held in open or closed position by a coil spring21, bearing atone end against the handle 20 and at its opposite endagainst a lug 22 on the wall 4.

The top plate 7 is reliably secured upon the walls 4 and 11 by lugs 23and bolts 24, the former being suitably secured to the wall 4, while thelatter extend through holes 7*, in the top plate 7 and through said lugs23. The top plate 7 is further held in place upon the walls 4 and 11 bydepending ribs 26 and 27 engaging the upper portions of said \walls 4and 11, respectively. The top plate 7 is provided with removable lids 28and 29'to leave openings for the reception of a wash boiler, or cookingutensils.

The attachment 1 is secured to the top flange B of the stove by twobolts 25, extending through registering holes-in said flange B and thewalls 3 and 12, as disclosed by Eig. 2. The attachment is centeredu npipe C.

did

is, preferably, left open, so that the products of combustion may passdirectly out into the stove pipe C through the outlets 17 and 9.

When the fire'is well underway the valve 18 is closed, so that theproducts of combustion after passing upward and heating that ortion ofthe top plate covering the top of inner chamber 10, will pass outthrough the outlet 16 and into the flue 13, where it divides and flowsin opposite directions through said flue to the outlet.9.- Thus it willbe-seen that the top plate'is heated in .a uniform manner throughout itsarea and will quickly heat flat irons,- or other domestic utensils lacedthereon. When desired one or both lids 28 may be removed to admit of thepassage of the lower portion of cooking utensils in there'sulta'ntopenings, and when it is desired to expose the bottom of a wash boilerdirectly to the heat inv the chamber 10, the lid 29 is also removed.

From the foregoing description it is apparent that I have produced anattachment for stoves which may be manufactured at 1 comparatively lowcost and possesses the features of advantage above enumerated, and whileI have shown the preferred construction, combination and arrangement ofparts, I reserve the right to make such changes as roperly fall withinthe spirit and scope o the claims.

Having thus desc bed my invention, what I claim and desire to secure byLetters Patent, is: a
